What does it mean to live in the 'authority' of Christ? It is both the ability to use God's power and the 'permission' to use it. We might believe we are given permission to use his power, but we might feel very 'unable' to do so. This is nothing but a lie from the pits of hell, my friends! We are given both - the ability and the 'authority' or 'permission' to tap into, live within, and use his power. To live 'powerless' lives is never the will of the Father - his will is for us to have ALL authority.
Did Jesus encounter times, places, and people who questioned his authority? Absolutely! Demons didn't want to submit to his authority, but a bunch of pig farmers lost their entire herd to one command to 'come out'! Sickness, crippling disease, and all manner of 'uncleanness' might have left many as outcasts from society for a long, long time, but none of these stood a chance when they encountered his authority! Insecure religious leaders who thought they had 'arrived' in the realm of their knowledge and power were left dumbfounded when he spoke with the power and authority of the Father who sent him.
We oftentimes 'operate' far below our potential as children of God, choosing a 'powerless' position in the face of our enemy's opposition. When we do, he wins! The power and authority of God Almighty resides within each of us - his presence is always with us - even when we might not feel or 'sense' it. God doesn't abandon his children - he commissions them, gives them both the POWER and the AUTHORITY to use it! If someone gave you the keys to the biggest box store, telling you that you could enter at will, take whatever you needed, and reorder all that was necessary for your life without any payment required, would you use them? Well, God gave us the keys to the Kingdom, and we might just hesitate to use them!
The authority we are given is 'backed' by the power of God. Authority without power to back it up is really nothing more than wishful thinking. If we have such 'powerful backing', isn't it time we started to use it to push back the forces of darkness in and around our lives? Just askin!
